FSD can be done without LIDAR, but the real question is - should it be done without it? It's the same with redundancy - when I drive my car, there is no redundancy so computer based systems technically don't need it as well, but is this a smart thing to do? NO. Can FSD be done using vision only ? Yes. Would it be safer to have Vision + Lidar? Most definitely. So why Musk won't do it? Cost + Ego + Time
